What machine are you thinking of buying? What services do you want to offer? I own a Bobcat T740 with high flow, I have a forestry mulching head, grapple, auger, grader, bucket and brush hog attachment. I like to offer wide range of services so I always stay busy. I want to teach you everything there is to know about each service, how I charge for a service, what’s my profit and very importantly I want to show you maintenance expenses. $5 bucks can make you thousands and save you thousands on maintenance fees.
